"We have to encourage the Germans to be more critical of the Israeli occupation," said Ruth Fructman, a Berlin journalist who was demonstrating.

"Right now it's still hard for them, especially because every time they criticize Israel, they're accused of anti-Semitism," she said.

Martin Vorberg, of the Middle Eastern Workgroup, said the demonstration was aimed at Osem Industries, which he said has a factory in the territories, and spices from Amnon and Tamar, a company located in Alfei Menashe.
